I'm not sure if this information is useful, but we have found one system which works with the 6.1 kernel. I grabbed the lspci output from a working and non-working system, pasted below. Same kernel and same distro. BAD Dell R815 AMD 0a:03.0 VGA compatible controller: Matrox Electronics Systems Ltd. MGA G200eW
Thanks for this info. That's a G200eW, which uses slightly different code within the driver. From the testing we've done, we didn't see the bug either. So it's probably something very specific to your machine or the G200EH model.
Best regards Thomas
